Update the full-replacement example graph to show the transitive
dependency that is required for the destroy-then-update case. Add
another example describing the case where we reduce the graph to
only an update and replace and the dependency on the destroy node
remains.
We currently count on interconnecting destroy nodes to handle the
create->destroy dependency edge for replacement, but when the create
node is only an update we don't connect that edge directly.
Lookup all creators that are dependencies of the destory node and ensure
they are connected.
Unfortunately at the moment I'm adding this the release isn't yet
available in the current version of goenv, but due to these including
security stuff and because we're about to make a Terraform release we're
letting this get slightly ahead of goenv on the assumption that it will
catch up shortly.
The traversal value is normally a valid HCL string, but can be
simplified if a traversal step has a complex index value (e.g. an
object). This means it is not always parseable HCL, so this commit
updates the documentation to clarify this and explicitly record that we
do not guarantee its contents are stable. The purpose of these values is
purely for building human-readable UI.
These aim to allow hinting to Terraform about situations where it's not
able to automatically infer value sensitivity.
"nonsensitive" is for situations where Terraform's behavior is too
conservative, such as when a new value is derived from a sensitive value
in such a way that all of the sensitive content is removed.
"sensitive", on the other hand, is for situations where Terraform can't
otherwise infer that a value is sensitive. These situations should be
pretty rare in a module that's making effective use of sensitive input
variables and output values, but the documentation shows one example of
an uncommon situation where a more direct hint via this function would
be needed.
Both of these functions are aimed at only occasional use in unusual
situations. They are here for reasons of pragmatism, not because we
expect them to be used routinely or recommend their use.
This is not currently a supported interface, but we plan to release
tool(s) that consume parts of it that are more dependable later,
separately from Terraform CLI itself.
In line with the other complex JSON output formats for plan and provider
schema, here we add an explicit `format_version` field to the JSON
output of terraform validate.
etcdv3 acceptance tests fail due to attempting to pass slices of strings
for the endpoints config to HCL2ValueFromConfigValue() which does not
handle that type.
Not a pretty solution but a helper function that converts the endpoints to a slice of
empty interfaces satisfies the requirements of the
HCL2ValueFromConfigValue function.

When migrating state to a new workspace, the version check would error
due to a 404 error on fetching the workspace record. This would result
in failed state migration.
Instead we should look specifically for a 404 error, and allow migration
to continue. If we're just about to create the workspace, there can't be
a version incompatibility problem.
* format/diff: extract attributes-writing logic to a function
This is a stepping-stone commit (for easier reviewability, and to prove that tests did not change) as part of writing a NestedType-specific diff printer.
* command/format: add support for formatting attributes with NestedTypes
This commit adds custom formatting for NestedType attributes. THe logic was mostly copied from the block diff printer, with minor tweaks here and there. I used the (excellent) existing test coverage and added a NestedType attribute to every test.
Since the (nested-block specific) test schemas were nearly identical, I added a function that returns the schema with the requested NestingMode.
If no default is specified for a nested optional structural typed
attribute, the defaults function should just pass through its input.
Before this commit the function assumed that the fallback value was
always of the correct type, which would panic.
Now that we have a comprehensive JSON diagnostic structure, we can use
it in the `validate -json` output instead of the inline version. Note
that this changes the output of `validate -json` in two ways:
1. We fix some off-by-one errors caused by zero-width highlight ranges.
This aligns the JSON diagnostic output with the text output seen by
most Terraform users, so I consider this a bug fix.
2. We add the `snippet` field to the JSON diagnostics where available.
This is purely additive and is permitted under our JSON format
stability guarantees.
This commit adds a comprehensive JSON format for diagnostics, which
ensures that all current diagnostic output can be semantically
represented in a machine-readable format. The diagnostic formatter
interface remains unchanged, but it first transforms its input via the
JSON format to ensure that there is only one code path for creating the
diagnostic data.
The JSON diagnostic renderer extracts the non-presentational logic from
the format package, and returns a structure which can either be
marshaled into JSON or rendered as text. The resulting text diagnostic
output is unchanged for all cases covered by unit tests and my own
manual testing.
Included in this commit are a number of golden reference files for the
marshaled JSON output of a diagnostic. This format should change rarely
if at all, and these are in place to ensure that any changes to the
format are intentional and considered.
This PR extends jsonprovider to support attributes with NestedTypes and extends test coverage in jsonprovider and the providers schemas tests. I've also cleaned up some comments and extracted the logic to parse the nesting mode so it can be used in both marshalling blocks and attributes.
When using defaults with a value which contains null objects or tuples,
we cannot continue to traverse the value and apply defaults. Instead,
when we find an attribute which is null, we return early and stop
processing this branch.
* Add helper suggestion when failed registry err
When someone has a failed registry error on init, remind them that
they should have required_providers in every module
* Give suggestion for a provider based on reqs
Suggest another provider on a registry error, from the list of
requirements we have on init. This skips the legacy lookup
process if there is a similar provider existing in requirements.
Fixes#27506
Add a new flag `-lockfile=readonly` to `terraform init`.
It would be useful to allow us to suppress dependency lockfile changes
explicitly.
The type of the `-lockfile` flag is string rather than bool, leaving
room for future extensions to other behavior variants.
The readonly mode suppresses lockfile changes, but should verify
checksums against the information already recorded. It should conflict
with the `-upgrade` flag.
Note: In the original use-case described in #27506, I would like to
suppress adding zh hashes, but a test code here suppresses adding h1
hashes because it's easy for testing.

The provider transformers remove extra provider nodes when they are
initially setup, but it may turn out that they are not used later on.
The pruneUnusedNodesTransformer takes care of removing unused expansion
nodes, which originally required a provider, and hence may cause some
provider nodes to no longer be needed. We can also detect these and
remove them during the pruneUnusedNodesTransformer process.
